There's a post here from Simon that might help:
https://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=655362#Post655362From the FAQ:
You might try changing the 'ASIO always on' setting in the Band-in-a-Box® ASIO Audio Drivers dialog to OFF. The ideal setting is ON, because this allows low latency play-thru while the song is stopped, however it may cause problems with some drivers when always on. Also, try setting the resampler quality to Fast. Band-in-a-Box® plays audio at 44.1 KHz sample rate, but some ASIO drivers only support higher sample rates, so Band-in-a-Box® automatically resamples the audio to the native format of the ASIO driver. Fast will use less processing power.
... suggests that if you can use WAS or MME, BiaB should be compatible with 48kHz hardware and if you must use ASIO, changing the resampler rate might help.
